The one thing I get out of workshops like that is to remember what it's like being a student - I take a whole set of notes to myself about what works from the student's perspective and what doesn't. It's sad to learn from someone else doing it wrong, but it really helps me to remember what it's like to sit in a chair for hours having to listen to other people talk at you, and to think what I can do to make that a lot more painless and interesting.
